Catalogued as CAS 5930-98-3, 4-(Trimethylsilyl)-3-butyn-2-one is a C7H12OSi alkyne carried in kilogram quantities.
Both alkyne carbons carry substituents, so the triple bond is carried through a route rather than functionalised at a terminal C-H. The protecting group is the reason the entry exists: it is carried through the steps that would otherwise attack the group underneath, and removed when that group is wanted.
The formula C7H12OSi resolves to 7 carbons with one oxygen and one silicon. At 7 carbons the entry is an oil or a low-melting solid, and it is handled at ambient temperature in most steps.
Handling and storage
The container is kept sealed and out of light. Alkynes are checked for the coupled diyne before use, because that is the impurity that builds on standing.
Ordering
Packing 1kg / 25kg / 100kg, with the batch COA, the SDS and a specification sheet suitable for incoming inspection travelling with the lot.
